# 1 1.0 INTRODUCTION

1.1 OVERVIEW

TRC Environmental Corporation (TRC) of Lowell, Massachusetts was retained by Dominion to perform EPA Utility MACT ICR testing at the Chesterfield Power Station located at 500 Coxendale Road in Chester, Virginia.

Testing was conducted for Unit 6 at the Ches ter Power Station for Dioxin/Furan HAPs. Triplicate test runs were performe d. Volumetric flow rate, the mois ture content of the stack gas, and oxygen and carbon dioxide concentrations were also measured during each test run. All testing was conducted while the unit was opera ting at “normal” load under steady state
conditions.

Sampling and analysis procedures described in this document we re conducted using procedures deemed acceptable by the United States Environm ental Protection Agency (USEPA). TRC was responsible for the collection and anal ysis of all flue gas samples.

Sampling and analysis was performed under the di rection of Mr. Tom Lundin of TRC’s Lowell,
Massachusetts office. Mr. Sean Warden a nd Mr. John Bowry of Do minion EMSG provided process and testing coordi nation at the facility.

1.2 SCOPE OF WORK

This section of the test protocol presents an overview of the scope of work and schedule associated with the testing of Unit 6 at the Chesterfield Power Station. The sample and analytical test matrix is presented in Table 1-1. The test program a pproach involved conducting
a series of three test runs at the Unit 6 stack outlet for various polluta nts, while the unit was operated at normal load under st eady-state conditions.

Testing was conducted for Dioxin/Furan HAPs. Th e results have been reported in lb/MMBtu,

# 6 2.0 SUMMARY OF RESULTS

Testing for the U.S. EPA Utility MACT ICR was conducted at Chesterfield Unit 6 between April 13, 2010 and April 15, 2010. As presented in Table 1-1, sampling for dioxin/furans was performed.

2.1 TEST RESULTS FOR DIOXIN/FURANS

Sampling for dioxin/furan organi cs emissions from Unit 6 wa s performed. The emission summary for dioxin/furan is presented in Tabl e 2-1a. The emission summary for PCBs is presented in Table 2-1b.

The Method 23 samples were received at the la boratory at a temperat ure of 11°C which is 5 degrees above the upper limit of the r ecommended storage temperature of 4  2°C. TRC has concluded that this temperature excursion has had little or no adverse effect on the PCDD/PCDF and PCB sample results. This conclusion has been based on the fact that all of the PCDD/PCDF field spike recoveries for all of the effected samples were within the 70 to 130% recovery objectives. The field spikes ar e labeled dioxin and furan isomer s that are spiked onto the XAD trap by the laboratory prior to shipping the trap s to TRC for sampling. The acceptable field spike recoveries provide evidence that the samples ha ve not exhibited any significant loss of the compounds of interest during shipping and handli ng as well as the exposur e to the exhaust gas matrix during sampling.L2010-2647Parameter UnitsSampling LocationDate ---Start Time ---Stop Time ---Net Sampling Time minutesSample Volume dscfStack Gas Flow Rate dscfmO2Concentration %2005 WHOToxic EquivalencyCongeners Factor 1Dioxin Isomers2,3,7,8 TCDD 1.0 < 1.9 ND < 1.9 < 3.4 ND < 3.4 < 3.3 ND < 3.3 < 2.9 ND < 2.9Total TCDD 0.0 < 1.9 ND < 0.0 < 3.4 ND < 0.0 < 3.3 ND < 0.0 < 2.9 ND < 0.01,2,3,7,8 PeCDD 1.0 < 1.8 ND < 1.8 < 3.2 ND < 3.2 3.80 3.80 < 2.9 < 2.9Total PeCDD 0.0 15.3 0.0 5.94 0.0 8.76 0.0 10.0 0.01,2,3,4,7,8 HxCDD 0.1 < 1.6 ND < 0.16 < 4.2 ND < 0.42 < 2.0 ND < 0.20 < 2.6 ND < 0.261,2,3,6,7,8 HxCDD 0.1 < 1.6 ND < 0.16 < 4.1 ND < 0.41 3.31 0.33 < 3.0 < 0.301,2,3,7,8,9 HxCDD 0.1 < 1.6 ND < 0.16 < 1.4 ND < 0.14 < 2.0 ND < 0.20 < 1.7 ND < 0.17Total HxCDD 0.0 < 1.6 ND < 0.0 9.13 0.0 11.7 0.0 < 7.5 < 0.01,2,3,4,6,7,8 HpCDD 0.01 < 2.2 ND < 0.02 < 2.7 ND < 0.03 < 3.3 ND < 0.03 < 2.7 ND < 0.03Total HpCDD 0.0 < 2.2 ND < 0.0 < 2.7 ND < 0.0 < 3.3 ND < 0.0 < 2.7 ND < 0.0Total OCDD 0.0003 < 12 ND < 0.004 < 8.0 ND < 0.002 < 9.1 ND < 0.003 < 9.7 ND < 0.003Sum pg < 33 --- < 29 --- < 36 --- < 33 ---Concentration pg/dscm@7% O2< 3.3 --- < 2.8 --- < 3.5 --- < 3.2 ---Emission Rate lb/MMBtu < 3.04E-12 --- < 2.55E-12 --- < 3.21E-12 --- < 2.93E-12 ---Emission Rate g/s < 2.56E-09 --- < 2.26E-09 --- < 2.80E-09 --- < 2.54E-09 ---Weighted Sum pg --- < 4.2 --- < 7.6 --- < 7.9 --- < 6.6Weighted Concentration pg/dscm@7% O2--- < 0.42 --- < 0.72 --- < 0.76 --- < 0.64Emission Rate lb/MMBtu < 3.87E-13 --- < 6.64E-13 --- < 6.97E-13 --- < 5.83E-13Weighted Emission Rate g/s --- < 3.27E-10 --- < 5.88E-10 --- < 6.08E-10 --- < 5.08E-10Furan Isomers2,3,7,8 TCDF 0.1 < 1.2 ND < 0.12 < 2.4 ND < 0.24 < 1.8 ND < 0.18 < 1.8 ND < 0.18Total TCDF 0.0 < 1.2 ND < 0.0 < 2.4 ND < 0.0 < 1.8 ND < 0.0 < 1.8 ND < 0.01,2,3,7,8 PeCDF 0.03 < 2.1 ND < 0.06 < 3.3 ND < 0.10 < 2.0 ND < 0.06 < 2.5 ND < 0.072,3,4,7,8 PeCDF 0.3 < 2.0 ND < 0.60 < 3.0 ND < 0.90 < 1.9 ND < 0.57 < 2.3 ND < 0.69Total PeCDF 0.0 < 2.1 ND < 0.0 < 3.3 ND < 0.0 < 2.0 ND < 0.0 < 2.5 ND < 0.01,2,3,4,7,8 HxCDF 0.1 < 2.5 ND < 0.25 < 2.4 ND < 0.24 < 1.8 ND < 0.18 < 2.2 ND < 0.221,2,3,6,7,8 HxCDF 0.1 < 2.3 ND < 0.23 < 2.3 ND < 0.23 < 1.7 ND < 0.17 < 2.1 ND < 0.212,3,4,6,7,8 HxCDF 0.1 < 2.3 ND < 0.23 < 2.3 ND < 0.23 < 1.7 ND < 0.17 < 2.1 ND < 0.211,2,3,7,8,9 HxCDF 0.1 < 2.6 ND < 0.26 < 2.6 ND < 0.26 < 1.9 ND < 0.19 < 2.4 ND < 0.24Total HxCDF 0.0 < 2.6 ND < 0.0 < 2.6 ND < 0.0 < 1.9 ND < 0.0 < 2.4 ND < 0.01,2,3,4,6,7,8 HpCDF 0.01 < 3.7 ND < 0.04 < 3.3 ND < 0.03 < 1.7 ND < 0.02 < 2.9 ND < 0.031,2,3,4,7,8,9 HpCDF 0.01 < 2.1 ND < 0.02 < 4.2 ND < 0.04 < 2.2 ND < 0.02 < 2.8 ND < 0.03Total HpCDF 0.0 < 2.1 ND < 0.0 < 4.2 ND < 0.0 < 2.2 ND < 0.0 < 2.8 ND < 0.0Total OCDF 0.0003 < 1.5 ND < 0.0005 < 2.7 ND < 0.001 < 1.4 ND < 0.0004 < 1.9 ND < 0.001Sum pg < 9.5 --- < 15 --- < 9.3 --- < 11 ---Concentration pg/dscm@7% O2< 0.95 --- < 1.4 --- < 0.90 --- < 1.1 ---Emission Rate lb/MMBtu < 8.74E-13 --- < 1.33E-12 --- < 8.24E-13 --- < 1.01E-12 ---Emission Rate g/s < 7.38E-10 --- < 1.18E-09 --- < 7.19E-10 --- < 8.78E-10 ---Weighted Sum pg --- < 1.8 --- < 2.3 --- < 1.6 --- < 1.9Weighted Concentration pg/dscm@7% O2--- < 0.18 --- < 0.22 --- < 0.15 --- < 0.18Emission Rate lb/MMBtu < 1.67E-13 --- < 1.99E-13 --- < 1.38E-13 --- < 1.68E-13Weighted Emission Rate g/s --- < 1.41E-10 --- < 1.76E-10 --- < 1.21E-10 --- < 1.46E-10TOTAL PCDD/PCDFng/dscm@7% O2--- < 0.001 --- < 0.0009 --- < 0.0009 --- < 0.001---Table 2-1a.

program.

## L2010-264 

# 13 4.3.1 Equipment Calibration

Inspection and calibration of th e equipment is a crucial step in ensuring the successful completion of the field effort. All equipment was inspected for proper operation and durability prior to calibration. Calibra tion of the following equipment was conducted in accordance with the procedures outlined in EPA documents entitled " Quality Assurance Handbook for Air Pollution Measurement Systems; Volume III - Stationary Source Specific Methods " and 40 CFR Part 60 Appendix A. Copies of the equipmen t calibration forms can be found in Appendix E. All calibrations were performed prior to the test program and included in the final report.

 Probe Nozzles (QA Handbook, Vol III, Section 3.4.2, pp. 19) - averaged three internal diameter measurements of th e nozzle; difference between high and low

 0.1 mm. Recalibrate, reshape and sharpe n when nozzle becomes nicked, dented or corroded.

 Pitot tubes (QA Handbook Vol III, S ection 3.1.2, pp. 1-13) - measured for appropriate spacing and dimensions or cal ibrated in a wind tunnel. Rejection criteria is given on the calibration sheet. A post-test check inspected for damage.

 Thermocouples (QA Handbook, Vol III, Section 3.4.2, pp. 12-18) – verified against a mercury-in-glass thermometer at three points including the anticipated measurement range. Acceptance limits - impinger + 2oF; DGM + 5.4oF; stack + 1.5 percent of stack temperature.

 Dry gas meters (EPA 40 CFR Part 60, Me thod 5, Section 5.3) - calibrated against a critical orifice. A cceptance criteria - pretest Y i 

# = Y = + 0.02; post test Y = + 0.05 Y i 

# .

 Field barometer (QA Handbook, Vol III, Section 3.4.2, pp. 18-19) – compared against a mercury-in-glass barometer or use Airport Station BP and correct for elevation. Acceptance criteria -

 0.02 in. Hg; post-test check will be the same.

 Analytical balances (QA Handbook, Vol III, Section 3.4.2, pp. 19) – Acceptance criteria - calibrate with Standard Class-S weights within

 0.5 mg of stated value. Corrective action: Have manuf acturer recalibrate or adjust.

4.3.2 Glassware Preparation

The sample train glassware necessary for the EPA Method 23 sampling train was precleaned in

## L2010-264 

# 14 accordance with the method. Special care was give n to the removal of re sidual silicone grease sealants on ground glass connect ions of used glassware.

4.3.3 Sample Media Preparation

All reagents were checked in accordance with the TRC’s existing QC Program to minimize the probability of using contaminated solvents. This included the use of spectro-grade solvents from the same lot and the collection and analysis of the appropriate blanks. All filters were desiccated and weighed to the nearest 0.5 mg constant weight.

XAD-2 ® 

# resin used in the Method 23 sampling trains was packed by the Field Sampling Subcontractor laboratory(s) in specially designed sorbent traps. The XAD-2 ® 

# resin was purchased pre-cleaned or prepared by the labora tory(s) to meet or ex ceed all quality control requirements specified in EP A Method 23, as applicable.

4.4 ONSITE SAMPLING ACTIVITIES

Onsite sampling activities includ ed conducting velocity traverses, moisture measurements, and sampling for dioxin/furans. Oxygen and carbon di oxide measurements were also made.

4.4.1 EPA Methods 1 and 2 for Velocity Measurements/Cyclonic Flow

Velocity traverses were conducted on the outle t stack with an S-type pitot assembly in
accordance with EPA Reference Methods 1 and 2. An S-type pitot tube with an attached
inclined manometer was used to measure the ex haust velocities at th e sampling location. An attached Type-K thermocouple with remote digita l display was used to determine the flue gas temperature. During the test program, velocity measurements were c onducted during each test run while operating the EPA Method 23, sampling trains. The required number of velocity measurements points for each sampling locati on was determined following EPA Method 1.
Cyclonic flow checks were conducted in accordan ce with Section 2.4 of EPA Method 1. This

## L2010-264 

# 15 procedure is referred to as the nulling technique. An S-type Pitot tube connected to an inclined
manometer was used in this method. The Pitot t ube was positioned at each traverse point so that the face openings of the P itot tube were perpendicular to the stack cross-sectional plane. This position is called the “0  reference”. The velocity pressure (  P) measurement is noted. If the  P reading was zero, the cyclonic angle was recorded as 0  . If the  P reading was not zero, the

Pitot tube was rotated clockwise or counter-clockwise until the  P reading became zero. This angle was then measured with a leveled protractor and reported to the near est degree. After this null technique was applied at each traverse po int, the average of the cyclonic angles was calculated. If this average was less than 20  , the flow condition wa s acceptable to test.

4.4.2 EPA Method 3A/3B for O2/CO2

Oxygen and carbon dioxide concentrations were determined at the sampling location for each test run in conjunction with a de signated sampling train in accordance with either EPA Method

3B “Gas Analysis for the Determination of Emis sion Rate Correction Factor or Excess Air.”

An integrated sample was collected in a Tedlar bag during each test r un. The sample gas was drawn through a stainless st eel probe and through Teflon  

# sampling line followed by a glass

condenser unit to remove excess moisture which would interfere with th e operation of the pump and flow meter. Approximately 20 liters of sample gas were co llected during each test run. Following completion of the test run, the sample s were given to Dominion plant personnel, for analyses. A sample from the Tedlar bag was dr awn into O2 and CO2 analyzers and immediately analyzed for percent CO 2 

# and percent O 2 

# . The analyzers had been cal ibrated in accordance with
EPA Method 3A.

The O2/CO2 concentrations were needed to calculate the flue gas molecular weight for determining volumetric flow rate as well as pr oviding the oxygen concen tration for correcting applicable emission rates to 7% O2.

## L2010-264 

# 16 4.4.3 EPA Method 4 for Moisture Determination

Moisture was determined for each test run according to EPA Reference Method 4,

" Determination of Moisture Content in Stack Gases ". The principle of this method is to remove the moisture from the sample stream and determine moisture either volumetrically or gravimetrically. Method 4 was used in conj unction with the acid gas sampling trains, semivolatile and formaldehyde tests, and the metals and particulate matte r sampling trains.

4.4.4 EPA Method 23 for Dioxin/Furan

A sampling train was used to measure and determin e the emission rate of select dioxins, furans, and PCBs during each test run in accordance with EPA Method 23, “ Determination of Polychlorinated Dibenzo-p-Diox ins and Polychlorinated Dibenzof urans from Municipal Waste

Combustors.” The sampling train consisted of a heat ed, glass-lined probe, with a glass buttonhook nozzle. A thermocouple and S-type Pitot tube attached to an inclined manometer were attached to the probe for measurement of gas te mperature and velocity. The sample gas passed through the probe assembly to a heated glass fiber filter. The heated, glas s-lined probe and filter holder were maintained at 248°F ±25°F throughout each test period. (Note: A heated transfer line of appropriate length was us ed between the sampling probe and the heated glass fiber filter
holder. This heated transfer line was maintained within the same temper ature range as the probe and filter holder.) Downstream of the heated filter, the gas passed through a water-cooled condenser module, then through a sorbent module containing 20 to 40 grams of XAD-2 ® 

# resin.
The XAD-2 ® 

# module was kept at a temperature belo w 68°F. The gas then passed through a
series of five ice-cooled im pingers kept below 68°F to enable condensation of entrained moisture. The first impinger, acting as a conde nsate reservoir connected to the outlet of the

XAD-2 ® 

# module, was modified with a short stem so that the sample gas did not bubble through the collected condensate. The next two impi ngers each contained 100 milliliters of deionized water. The fourth impinger was empty and the fifth impinger contained a preweighed amount of silica gel. All connec tions within the train were glass or Teflon ® 

# . No sealant greases were used. The impingers were followed by a dry gas meter, pump, and calibrated orifice meter.

## L2010-264 

# 17 One sample was collected for each test run. E ach sample was collected over an eight-hour period. Sampling was isokinetic (±10 percent) with readings of exhaust gas parameters recorded at every sampling point during the traverse. Thes e readings included the ti me, velocity, pressure, the target orifice pressure, the ac tual orifice pressure, stack gas temperature, probe temperature, filter temperature, heated transfer line temperatur e, sorbent trap temperature, silica gel impinger temperature, dry gas meter inlet and outlet te mperatures, dry gas meter volume, and sample

vacuum.

Leak checks of the entire EPA Method 23 samp ling train were performed before and after sampling in each port. In the event any portion of the train was disassembled and reassembled, leak checks were performed prior to disassemb ling, and following reassembly of the train. All leak checks and leakage rates were documented on the relevant field test data sheet. The acceptance criteria for the EPA Met hod 23 train was a leak rate of  0.02 cubic feet per minute at a vacuum equal to or greater than the ma ximum value reached during the sampling run.

Following the completion of each test run, the sampling train was leak checked and then transported to a recovery area on-site. Th e sample recovery sequence was as follows:

 

# Noted the condition of the train (i.e., filter c ondition, color of impinger contents, color of silica gel, etc.).

 

# Filter - The filter was removed carefully from the filter holder and placed in its original glass petri dish. Cleaned tweezers were used to handle the filter. The filter was folded, if necessary, with the particulate cake inside the fold. Any particulate matter and filter fibers that adhered to the filter holder gasket were transferred to the container by using a dry inert bristle brush and a sharp-edged blad e. The container was sealed with Teflon ® 

# tape and labeled with the appropriate sample information.

 

# Sorbent module - The XAD-2 ® 

# resin sorbent module was rem oved from the train, tightly capped at both ends with Teflon ® 

# tape and aluminum foil, labeled and stored on-site on ice, or equivalent, for trans port to the laboratory. Care wa s taken to ensure that no ice water leaked into the stored tr aps or any other train component.

 

# Front-half rinse - Material depos ited in the nozzle, probe liner, heated transfer line, and the front half of the filter holder was quantitat ively recovered. To prevent contamination of the sample, all openings were sealed with Teflon tape just after sample train disassembly and until recovery was about to begin. In addition, nitrile gloves were worn during all recovery procedures and all recovery solvents were stored in appropriate

## L2010-264 

# 18 containers. The train components were br ushed while rinsing three times each with acetone. The outside of the probe, the Pitot t ube, and the nozzle were cleaned to prevent particulates from being brushed into the sa mple bottle. The probe liner was tilted and rotated while squirting acetone into the upper end to assure complete wetting of the inside surface. Acetone was then squirted into the upper end while pushing the probe brush through the liner with a twisting motion, with th e drainage caught in the sample bottle. The brushing procedure was repeated two more times or until no particles were visible in the drainage and a visual inspection of the lin er revealed no particles remaining inside. The heated transfer line was rinsed and brushed through the en tire length of the line with acetone. All rinsate was collected into the same container. The brush was rinsed into the sample bottle to collect any particulates that ma y have been retained within the bristles.

 

# Back-half rinse - The back half of the filter holder, the connecting line between the filter holder and the condenser, and the condenser itself (if separate from the trap) were rinsed three times with acetone. These rinses were a dded to the same container as the front-half rinses.

 

# Front-half and Back-half rinses with toluen e – Repeated the acetone rinses described above using toluene as the rinse solvent. These rinses were collected in a separate container. After all the rinses had been co llected, the lid on the sample containers was tightened securely. As a precaution in case of leakage, the liquid level was marked on the sample container and the cap sealed with Teflon ® 

# tape.

 

# Impinger water (first four impingers) - Any co lor or film in the impinger water was noted on the sample recovery form. The entrained moisture in the first four impingers was measured to within ±1 milliliter by using a graduated cylinder or by weighing to within 0.5 grams, and the data recorded appropriatel y. This information was used to calculate the moisture content of the effluent gas. The impinger liquid from the second, third and fourth impingers was discarded after the volume or weight is recorded.

 

# The condensate from the first impinger was placed in a sample container. More than one container was used, if necessary. The conde nsate knockout was then rinsed three times each with acetone and methylene chloride into the same container used to collect the condensate. [Note: The condensate rinse should not be collected into the same container as the back-half rinses to preclude introducti on of condensate fractions, which were to be analyzed for PCBs only, to the back-half fraction, which was to be analyzed for dioxins and furans in addition to PCBs. In additi on, the use of toluene was not indicated for rinsing of the condensate impinger as methyl ene chloride is an effective solvent for capturing any PCBs present and to preclude th e introduction of toluene into this sample fraction as it could unnecessarily complicate the extraction of this sample fraction.]

 

# Silica gel (fifth impinger) - The color of the indicating silica gel was noted on the recovery form to determine if it had been completely spent. The impinger was weighed to within ±0.5 grams using a triple beam balan ce, or equivalent. The gain in weight was used for moisture calculations. Analysis was not required.

## L2010-264 

# 19  

# All containers were checked to ensure prope r sealing, proper labeli ng and that all liquid levels were marked. All samples were th en logged onto a chai n-of-custody record.

The EPA Method 23 train yiel ded the following samples:

 

# Filter,

 

# XAD-2 ® 

# module,

 

# Front-half and Back-half Acetone solvent rinse, and

 

# Front-half and Back-half Toluene solvent rinse

For the purpose of PCB analysis of this combined sampling train, the filter and front-half solvent rinse were combined to form a sample fraction for analysis (i.e., the front-half fraction). The
XAD-2® module and back-half solven t rinse fractions were extracte d to form a sample fraction for analysis (i.e., the back-half fraction).

# 23 6.0 QUALITY ASSURANCE

6.1 OVERVIEW

TRC Environmental Corporation management is fully committed to an effective Quality Assurance/Quality Control Program whose objective is the delivery of a quality product. For much of TRC's work, that product is data re sulting from field measurements, sampling and analysis activities, engineering assessments, and the analysis of gathered data for planning purposes. The Quality Assurance Program works to provide complete, precise, accurate, representative data in a timely manner for each project, considering both the project's needs and budget constraints.

This section highlights the specific QA/QC procedur es that were followed for this Test Program.

6.2 FIELD QUALITY CONTROL SUMMARY

6.2.1 Calibration Procedures

Calibration of the field sampling equipment was pe rformed prior to the field sampling effort. Copies of the calibration sheets were submitted to th e field team leader to take onsite and placed into the project file. Calibr ations were performed as described in the EPA publications " Quality Assurance Handbook for Air Pollution Measuremen t Systems; Volume III - Stationary Source Specific Methods " and EPA 40 CFR Part 60 Appendix A. Equipment to be calibrated included the sample metering system, nozzles, barometers, thermocouples, and Pitot tubes. All calibrations were available for review during the te st program. Copies of the example equipment calibration forms are presented found in Appendix E.

## L2010-264 

# 24 6.2.2 Equipment Leak Checks

Prior to sampling, each sampling train was leak checked according to the procedures outlined in
EPA Reference Method 23. Final leak checks were performed to ensure that no leaks develop in the train during the course of each test run. All leakage rates, if any found, were recorded on the appropriate field data sheet.

6.2.3 Cyclonic Flow Check

The absence of cyclonic flow at the stack was es tablished prior to sampling, in accordance with
Section 2.4 of EPA Method 1.

6.2.4 Method Blanks

One Method blank for the Methods 23 sampling train was collected duri ng the field-sampling program to ensure sample quality.

6.3 SAMPLE CHAIN OF CUSTODY

Chain-of-custody of the samples were initiated and mainta ined as follows:

• Each sample that was collected was labe led, sealed, and the liquid level marked on appropriate samples. • Each sample was recorded on the chain-of-custody form. • Custody of the samples were retained by T RC until delivery to the analytical laboratory for analysis.

6.4 DATA REDUCTION, VALI DATION, AND REPORTING

Specific QC measures were used to ensure th e generation of reliable data from sampling and analysis activities. Proper co llection and organization of accur ate information followed by clear and concise reporting of the data is a primary goal in all projects.

## L2010-264 

# 25 6.4.1 Field Data Reduction

The Field Team Leader and at least one other fi eld crewmember reviewed the data collected in the field. Any recording errors or discrepancies were noted on the field da ta sheet. The field sampling data sheets are presented in Appendix A.

6.4.2 Laboratory Analysis Data Reduction

Analytical results were reduced to concentrati on units specified by the analytical procedures, using the equations provided in the analytical procedures.

6.4.3 Data Validation

TRC supervisory and QC personnel use validation me thods and criteria appropr iate to the type of data and the purpose of the measurement. Record s of all data were maintained, including any judged to be an "outlying" or s purious value. The persons who va lidated the data have sufficient knowledge of the technical work to identify questionable values.

The Field Team Leader and/or the Field QC Coor dinator based on their re view of the adherence to an approved sampling protocol and written sample collection procedure validated fieldsampling data.

Analytical data were validated using criteria out lined below. TRC utilized results from the field method blank to further validate analytical result s. Furthermore, TRC reviewed all laboratory raw analytical data to verify th e calculated results presented.

The following criteria were used to evaluate the field sampling data: • Use of approved test procedures; • Proper operation of th e process being tested; • Use of properly operating and calibrated equipment; • Leak checks conducted before and after tests; • Use of reagents conforming to QC specified criteria;
